By now, most people probably know that it’s a bad idea to mess with UFC champ Ronda Rousey. Actor Ken Jeong learned this the hard way.

Rousey recently guest-anchored SportsCenter, where she threatened Jeong for apparently spoiling a major Game of Thrones plot point for her at the ESPYs in July.

“You know, I’ve been waiting to run into you for a while,” Rousey tells Jeong, venom dripping from her voice. Jeong beings to cower in fear—jokingly, of course, but he’s clearly aware that Rousey could seriously, seriously hurt him.

“Don’t say anything else about the show or the books to try and make up for it,” Rousey warns, “or else I will find where you’re at and I will shank you with this pen. Say nothing.”

Sounds like she’d fit right in with the rest of Westeros.
